jgrusewski 727ed0d43b refactor: remove use_qr_dqn — IQN always enabled via iqn_lambda
use_qr_dqn was a hacky toggle that gated the IQN dual-head behind
a num_atoms threshold. IQN is now always enabled when iqn_lambda > 0
(default 0.25). C51 remains the main loss; IQN is the auxiliary head
for CVaR risk quantification.

Removed use_qr_dqn from: DQNParams, DQNHyperparameters, fused_training,
hyperopt adapter, all tests, all examples.
